Lead is a common impurity found in zinc ores, often occurring alongside zinc deposits in nature. It is often separated from zinc during the purification process. Zinc smelting typically involves the reduction of zinc oxide with carbon, which can also reduce other impurities such as cadmium and silver, leaving lead as the most likely principal impurity.
